Ditech 17 dBm Full Band Line Amplifier: (Quasar 1723)

Product Outline

The Quasar optical amplifier is a third generation amplifier. The Quasar optical amplifier adds gain control and transient suppression to a previous generation of amplifiers and enables optical signals to be added/dropped from a DWDM network span without degradation of other optical signals in the same span. Quasar is a key technology for bandwidth-on-demand and wavelength protection switching. Key Features
